Check the new MD88/MD90 newsletter, it just came up in my email this evening. The said the MD88/90 Strategic Flight Deck Refresh (GPS, dual FMS and Flat Panel Display) has been approved and installations will begin in 2014 and continue to the end of 2015.
The airplane will be able to fly curved approaches...wait... it does that now... I don't know, they must be confused. RNAV RNP approaches. BTW, you know what a Fed once told me about RNP-2? It means you have to have 2 FMSs.

I want to see an RNP-10 cockpit.
Anyways, full datalink including flight plane, performance and takeoff data uplinks. NextGen and CPDLC!!!!
AWESOME! ETOPS MD-88'S!!!! Bar has to be excited. ADS-B and Traffic Information. YEAH!!!!!!!! For those of you who fly the newly acquired MD-90s, mandarin dogs as one pilot said, that means we'll finally know what traffic is out there beyond 6.5 miles!!!
Anyways, better cockpit and their words not mine, it will be simplified and more capable than many of our newer widebody aircraft.
Somebody pick Bar off the floor.
Check it out, it is online. For those of you who are not familiar with the MD-88 newsletter, you can find it by clicking on the picture of the jumbo RJ looking airplane on Deltanet and then finding the newsletter.
